AISI 6150 Heat Treat

[mfgenggear]

It would be nice if some one could share after though harden heat treat data of actual parts contraction or expansion.

We are making a hollow gear shafts about 6" long
Unfortunately, I cannot post a print because of customer proprietary issues. Through Harden Heat Treat to 44HRc.
AISI 6150 Steel

I am looking for actual inch per inch expansion or contraction.
Any issues with distortion.

Thanks
